Why Ice Cream Was Once a Luxury

Ice cream was once a luxury. The breakthrough that made it an everyday treat was bigger than a better recipe: it was learning to control cold. From winter icehouses and Thomas Jefferson's handwritten recipe to Nancy Johnson's hand-crank freezer, mechanical refrigeration, and today's cold chain, this documentary follows the technology and labor behind an ordinary scoop. Discover why salt helped freeze ice cream, why sugar does more than sweeten it, how air and tiny ice crystals shape its texture, and why a freezer at the factory is only the beginning of the journey. This episode follows the European and American branch of dairy ice cream history. It does not claim that one person invented every kind of frozen dessert. What's your favorite ice cream flavor?
